Human herpesvirus 6A and axonal injury before the clinical onset of multiple sclerosis.

Recent research indicates that multiple sclerosis is preceded by a prodromal phase with elevated levels of serum neurofilament light chain (sNfL), a marker of axonal injury. The effect of environmental risk factors on the extent of axonal injury during this prodrome is unknown. Human herpesvirus 6A (HHV-6A) is associated with an increased risk of developing multiple sclerosis. The objective of this study was to determine if HHV-6A serostatus is associated with the level of sNfL in the multiple sclerosis prodrome, which would support a causative role of HHV-6A. A nested case-control study was performed by crosslinking multiple sclerosis registries with Swedish biobanks. Individuals with biobank samples collected before the clinical onset of multiple sclerosis were included as cases. Controls without multiple sclerosis were randomly selected, matched for biobank, sex, sampling date and age. Serostatus of HHV-6A and Epstein-Barr virus was analysed with a bead-based multiplex assay. The concentration of sNfL was analysed with single molecule array technology. The association between HHV-6A serology and sNfL was assessed by stratified t-tests and linear regressions, adjusted for Epstein-Barr virus serostatus and sampling age. Within-pair ratios of HHV-6A seroreactivity and sNfL were calculated for each case and its matched control. To assess the temporal relationship between HHV-6A antibodies and sNfL, these ratios were plotted against the time to the clinical onset of multiple sclerosis and compared using locally estimated scatterplot smoothing regressions with 95% confidence intervals (CI). Samples from 519 matched case-control pairs were included. In cases, seropositivity of HHV-6A was significantly associated with the level of sNfL (+11%, 95% CI 0.2-24%, P = 0.045) and most pronounced in the younger half of the cases (+24%, 95% CI 6-45%, P = 0.007). No such associations were observed among the controls. Increasing seroreactivity against HHV-6A was detectable before the rise of sNfL (significant within-pair ratios from 13.6 years versus 6.6 years before the clinical onset of multiple sclerosis). In this study, we describe the association between HHV-6A antibodies and the degree of axonal injury in the multiple sclerosis prodrome. The findings indicate that elevated HHV-6A antibodies both precede and are associated with a higher degree of axonal injury, supporting the hypothesis that HHV-6A infection may contribute to multiple sclerosis development in a proportion of cases.

Altered probe pressure and body position increase diagnostic accuracy for men and women in detecting hepatic steatosis using quantitative ultrasound.

OBJECTIVES: To evaluate the diagnostic performance of ultrasound guided attenuation parameter (UGAP) for evaluating liver fat content with different probe forces and body positions, in relation to sex, and compared with proton density fat fraction (PDFF). METHODS: We prospectively enrolled a metabolic dysfunction-associated steatotic liver disease (MASLD) cohort that underwent UGAP and PDFF in the autumn of 2022. Mean UGAP values were obtained in supine and 30° left decubitus body position with normal 4 N and increased 30 N probe force. The diagnostic performance was evaluated by the area under the receiver operating characteristic curve (AUC). RESULTS: Among 60 individuals (mean age 52.9 years, SD 12.9; 30 men), we found the best diagnostic performance with increased probe force in 30° left decubitus position (AUC 0.90; 95% CI 0.82-0.98) with a cut-off of 0.58 dB/cm/MHz. For men, the best performance was in supine (AUC 0.91; 95% CI 0.81-1.00) with a cut-off of 0.60 dB/cm/MHz, and for women, 30° left decubitus position (AUC 0.93; 95% CI 0.83-1.00), with a cut-off 0.56 dB/cm/MHz, and increased 30 N probe force for both genders. No difference was in the mean UGAP value when altering body position. UGAP showed good to excellent intra-reproducibility (Intra-class correlation 0.872; 95% CI 0.794-0.921). CONCLUSION: UGAP provides excellent diagnostic performance to detect liver fat content in metabolic dysfunction-associated steatotic liver diseases, with good to excellent intra-reproducibility. Regardless of sex, the highest diagnostic accuracy is achieved with increased probe force with men in supine and women in 30° left decubitus position, yielding different cut-offs. CLINICAL RELEVANCE STATEMENT: The ultrasound method ultrasound-guided attenuation parameter shows excellent diagnostic accuracy and performs with good to excellent reproducibility. There is a possibility to alter body position and increase probe pressure, and different performances for men and women should be considered for the highest accuracy. KEY POINTS: • There is a possibility to alter body position when performing the ultrasound method ultrasound-guided attenuation parameter. • Increase probe pressure for the highest accuracy. • Different performances for men and women should be considered.

A comparative trial of blood pressure monitoring in a self-care kiosk, in office, and with ambulatory blood pressure monitoring.

BACKGROUND: Automated measurement of blood pressure (BP) in designated BP kiosks have in recent years been introduced in primary care. If kiosk blood pressure (BP) monitoring provides results equivalent to in-office BP or daytime ambulatory BP monitoring (ABPM), follow-up of adult patients could be managed primarily by self-checks. We therefore designed a comparative trial and evaluated the diagnostic performance of kiosk- and office-based BP (nurse- versus physician-measured) compared with daytime ABPM. METHODS: A trial of automated BP monitoring in three settings: a designated BP kiosk, by nurses and physicians in clinic, and by ABPM. The primary outcome was systolic and diastolic BP, with respective diagnostic thresholds of ≥135 mmHg and/or ≥ 85 mmHg for daytime ABPM and kiosk BP and ≥ 140 mmHg and/or ≥ 90 mmHg for office BP (nurse- and physician-measured). RESULTS: Compared with daytime ABPM, mean systolic kiosk BP was higher by 6.2 mmHg (95% confidence interval [CI] 3.8-8.6) and diastolic by 7.9 mmHg (95% CI 6.2-9.6; p < 0.001). Mean systolic BP taken by nurses was similar to daytime ABPM values (+ 2.0 mmHg; 95% CI - 0.2-4.2; p = 0.071), but nurse-measured diastolic values were higher, by 7.2 mmHg (95% CI 5.9-9.6; p < 0.001). Mean systolic and diastolic physician-measured BPs were higher compared with daytime ABPM (systolic, by 7.6 mmHg [95% CI 4.5-10.2] and diastolic by 5.8 mmHg [95% CI 4.1-7.6]; p < 0.001). Receiver operating characteristic curves of BP monitoring across pairs of systolic/diastolic cut-off levels among the three settings, with daytime ABPM as reference, demonstrated overall similar diagnostic performance between kiosk and nurse-measured values and over the curve performance for physician-measured BP. Accuracy with nurse-measured BP was 69.2% (95% CI 60.0-77.4%), compared with 65.8% (95% CI 56.5-74.3%) for kiosk BP. CONCLUSIONS: In this study kiosk BP monitoring was not comparable to daytime ABPM but could be an alternative to in-office BP monitoring by trained nurses. The diagnostic performance of kiosk and nurse-measured BP monitoring was similar and better than that of physician-measured BP. TRIAL REGISTRATION: ClinicalTrials.gov (NCT04488289) 27/07/2020.

Minimum important difference of the ICIQ-UI SF score after self-management of urinary incontinence.

BACKGROUND: This study aimed to evaluate clinically relevant improvement after conservative self-management of urinary incontinence via a mobile app. It further aimed to establish Minimum Important Differences (MIDs) based on the severity and type of urinary incontinence. METHODS: Data was collected in a prospective cohort study that evaluated the freely available app Tät®. The app provided pelvic floor muscle training (PFMT) and life-style advice. Non-pregnant, non-postpartum women (≥ 18 years) who downloaded the app to treat urinary incontinence were included, if they completed the Patient Global Impression of Improvement (PGI-I) question at the 3-month follow-up (n = 1,733). Participants answered the International Consultation on Incontinence Questionnaire (ICIQ-UI SF) at baseline and after 3 months. The score change was analysed for correlation (Spearman) with the PGI-I. We then analysed one-way ANOVAs to determine whether there were significant differences between the groups based on the answers to the PGI-I. The MID was set to the mean change of the group that selected the answer "a little better" to the PGI-I question. RESULTS: The one-way ANOVA showed significant differences between PGI-I groups (p < 0.001). The MID for the general group was set to 1.46 (95% Confidence Interval [CI] 1.26-1.67). In the sub-group analyses, a MID for the group with slight incontinence could not be determined. For the group with moderate severity the MID was determined to be 1.33 (95% CI 1.10-1.57) and for the severe/very severe group it was 3.58 (95% CI 3.08-4.09). Analysis of different types of incontinence showed no difference in MIDs. CONCLUSIONS: The MID for self-management via a mobile app was lower than previously established MIDs, but differed depending on baseline severity. This study shows that MIDs need adjustment for baseline severity and treatment intensity when interpreting clinical trial results. If using MIDs as exact numbers, the study population and the treatment must be comparable.

Adolescents on psychotropic treatment displayed longer corrected QT intervals than unmedicated controls when they rose rapidly from the supine position.

AIM: Psychotropic medication can contribute to arrhythmia and identifying individuals at risk is crucial. This Swedish study compared the corrected QT (QTc) intervals of adolescents on psychotropic medication with unmedicated controls, when supine and after rising rapidly. METHODS: The study was carried out at Östersund County Hospital in March 2022 and February to March 2023. It comprised 16 cases, aged 10-17 years and 28 controls. QTc intervals were measured with electrocardiography and calculated using Bazett's and Fridericia's formulas. Univariate and multiple linear regressions were used to assess differences in QTc intervals between the cases and controls and across sex, age and body mass index. RESULTS: The mean QTc interval when supine, calculated with Bazett's formula, was longer for the adolescents on psychotropic medication than the controls (p = 0.046). The same was true for the mean QTc interval after rising rapidly from the supine position, calculated with both Bazett's formula (p = 0.009) and Fridericia's formula (p = 0.007). Mean QTc intervals varied by sex and age groups. Psychotropic medication prolonged QTc intervals, particularly in girls. CONCLUSION: Longer QTc intervals were found in adolescents on psychotropic medication, particularly after rising rapidly from the supine position.

APP-based treatment of urgency and mixed urinary incontinence in women: factors associated with long-term satisfaction.

PURPOSE: App-based treatment of urgency (UUI) and mixed (MUI) urinary incontinence has proved to be effective. To further improve treatment, it will be beneficial to analyze baseline and treatment-related factors that are associated with satisfaction. METHODS: A secondary analysis was conducted of data from a randomized controlled trial (RCT) assessing an app for UUI or MUI treatment, encompassing 98 women for whom there was long-term treatment satisfaction data. All participants completed a short-term (15 weeks) and a long-term (15 months) follow-up questionnaire after being given access to treatment. The outcome was a 3-item question on current treatment satisfaction at the long-term follow-up. Factors potentially associated with the outcome were analyzed using the chi-square test, Student's t test or logistic regression. RESULTS: At the long-term follow-up, 58% of the women were satisfied with the treatment. The most important baseline variable associated with satisfaction was incontinence-related quality of life (International Consultation on Incontinence Questionnaire (ICIQ) - Lower Urinary Tract Symptoms Quality of Life Module) (OR 0.91, 95% CI 0.58-0.97). Short-term follow-up variables associated with long-term treatment satisfaction were improvement in the ability to endure urgency (OR 4.33, 95% CI 1.43-13.12), and confidence in pelvic floor contraction ability (OR 2.67, 95% CI 1.04-6.82). CONCLUSION: App-based treatment for UUI and MUI may be an alternative first-line treatment that is satisfactory to many women over the long-term. Furthermore, short-term treatment that focuses on improving the ability to endure urgency, and confidence in pelvic floor contraction ability, can also be recommended for long-term satisfaction.

Sonographic postpartum anal sphincter defects and the association with pelvic floor pain and dyspareunia.

INTRODUCTION: Pelvic floor pain and dyspareunia are both important entities of postpartum pelvic pain, often concomitant and associated with perineal tears during vaginal delivery. The association between postpartum sonographic anal sphincter defects, pelvic floor pain, and dyspareunia has not been fully established. We aimed to determine the prevalence of postpartum anal sphincter defects using three-dimensional endoanal ultrasonography (3D-EAUS) and evaluate their association with symptoms of pelvic floor pain and dyspareunia. MATERIAL AND METHODS: This prospective cohort study followed 239 primiparas from birth to 12 months post delivery. Anal sphincters were assessed with 3D-EAUS 3 months postpartum, and self-reported pelvic floor function data were obtained using a web-based questionnaire distributed 1 year after delivery. Descriptive statistics were compared between the patients with and without sonographic defects, and the association between sonographic sphincter defects and outcomes were analyzed using logistic regression. RESULTS: At 3 months postpartum, 48/239 (20%) patients had anal sphincter defects on 3D-EAUS, of which 43 (18%) were not clinically diagnosed with obstetric anal sphincter injury at the time of delivery. Patients with sonographic defects had higher fetal weight than those without defects, and a perineum <2 cm before the suture was a risk factor for defects (odds ratio [OR], 6.9). Patients with sonographic defects had a higher frequency of dyspareunia (OR, 2.4), and pelvic floor pain (OR, 2.3) than those without defects. CONCLUSIONS: Our results suggest an association between postpartum sonographic anal sphincter defects, pelvic floor pain, and dyspareunia. A perineal height <2 cm, measured by bidigital palpation immediately postdelivery, was a risk factor for sonographic anal sphincter defect. We suggest offering pelvic floor sonography around 3 months postpartum to high- risk women to optimize diagnosis and treatment of perineal tears and include perineum <2 cm prior to primary repair as a proposed indication for postpartum follow-up sonography.

Longitudinal neuropsychological trajectories in idiopathic normal pressure hydrocephalus: a population-based study.

BACKGROUND: Idiopathic normal pressure hydrocephalus (iNPH) is a progressive syndrome affecting gait, incontinence, and cognition in a significant number of older adults. Still, prospective studies on early development of symptoms are scarce. AIM: To investigate how neuropsychological functions develop before and in already diagnosed iNPH over a two-year period in a population-based material. METHOD: A sample of 104 participants (median [IQR] 75 [72-80] years old) from the general population underwent CT-imaging and clinical assessment at baseline and follow-up. We used the iNPH symptom scale covering four domains (Neuropsychology, Gait, Balance, Incontinence) and additional tests of executive functions. Morphological signs were rated with the iNPH Radscale. Non-parametric statistics with Bonferroni corrections and a significance-level of p < 0.05 were used. RESULTS: Median (IQR) time to follow-up was 25 (23-26) months. Effect size (ES) for individuals who developed iNPH (n = 8) showed a large (ES r = -0.55) decline in the Gait domain and on the Radscale (ES r = -0.60), with a medium deterioration in declarative memory (ES r = -0.37). Those having iNPH at baseline (n = 12) performed worse on one executive sub-function i.e., shifting (p = 0.045). CONCLUSION: Besides deterioration in gait and radiology, our results suggest that a neuropsychological trajectory for those developing iNPH includes a reduction in declarative memory. Executive dysfunction was limited to those already having iNPH at baseline. These findings could suggest that memory impairments are included in the early development of iNPH.

Persisting symptoms after Cryptosporidium hominis outbreak: a 10-year follow-up from Östersund, Sweden.

In late 2010, an outbreak of Cryptosporidium hominis affected 27,000 inhabitants (45%) of Östersund, Sweden. Previous research shows that abdomen and joint symptoms commonly persist up to 5 years post-infection. It is unknown whether Cryptosporidium is associated with sequelae for a longer duration, how persisting symptoms present over time, and whether sequelae are associated with prolonged infection. In this prospective cohort study, a randomly selected cohort in Östersund was surveyed about cryptosporidiosis symptoms in 2011 (response rate 69.2%). A case was defined as a respondent reporting new diarrhoea episodes during the outbreak. Follow-up questionnaires were sent after 5 and 10 years. Logistic regressions were used to examine associations between case status and symptoms reported after 10 years, with results presented as adjusted odds ratios (aOR) with 95% confidence intervals. Consistency of symptoms and associations with case status and number of days with symptoms during outbreak were analysed using X2 and Mann-Whitney U tests. The response rate after 10 years was 74% (n = 538). Case status was associated with reporting symptoms, with aOR of ~3 for abdominal symptoms and ~2 for joint symptoms. Cases were more likely to report consistent symptoms. Cases with consistent abdominal symptoms at follow-up reported 9.2 days with symptoms during the outbreak (SD 8.1), compared to 6.6 days (SD 6.1) for cases reporting varying or no symptoms (p = 0.003). We conclude that cryptosporidiosis was associated with an up to threefold risk for reporting symptoms 10 years post-infection. Consistent symptoms were associated with prolonged infection.

Free vitamin D3 index and vitamin D-binding protein in multiple sclerosis: A presymptomatic case-control study.

BACKGROUND AND PURPOSE: High levels of 25-hydroxyvitamin D3 (25[OH]D3 ) are associated with a lower risk for multiple sclerosis (MS). The bioavailability of 25(OH)D3 is regulated by its main plasma carrier, vitamin D-binding protein (DBP). Free 25(OH)D3 can be estimated by also measuring DBP concentration. In addition, DBP has immunomodulatory functions that may independently affect MS pathogenesis. No previous studies have assessed free 25(OH)D3 or DBP in presymptomatically collected samples. This study was undertaken to assess free 25(OH)D3 and DBP as risk factors for MS. METHODS: A nested case-control study was performed with presymptomatic serum samples identified through cross-linkage of MS registries and Swedish biobanks. Concentration of 25(OH)D3 was measured with liquid chromatography and DBP levels with sandwich immunoassay. Free 25(OH)D3 was approximated as free vitamin D3 index: (25[OH]D3 /DBP) × 103 . MS risk was analyzed by conditional logistic regression, calculating odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: Serum samples from 660 pairs of matched cases and controls were included. At <20 years of age, high levels of free vitamin D3 index were associated with a lower risk of MS (highest vs. lowest quintile: OR = 0.37, 95% CI = 0.15-0.91, p for trend across quintiles = 0.04). At age 30-39 years, high levels of DBP were associated with a lower MS risk (highest vs. lowest quintile: OR = 0.36, 95% CI = 0.15-0.85, p for trend = 0.02). CONCLUSIONS: These findings support the hypothesis that high levels of free 25(OH)D3 at a young age reduce the risk of MS later in life. They also implicate a role for DBP in MS etiology.

Increased incidence of late-onset inflammatory bowel disease and microscopic colitis after a Cryptosporidium hominis outbreak.

OBJECTIVES: In 2010, 27,000 inhabitants (45% of the population) of Östersund, Sweden, contracted clinical cryptosporidiosis after drinking water contaminated with Cryptosporidium hominis. After the outbreak, local physicians perceived that the incidence of inflammatory bowel disease (IBD), including ulcerative colitis (UC), Crohn's disease (CD), and IBD-unclassified, and microscopic colitis (MC) increased. This study assessed whether this perception was correct. MATERIALS AND METHODS: This observational study included adult patients (≥18 years old) from the local health care region who were diagnosed with pathology-confirmed IBD or MC during 2006-2019. We collected and validated the diagnosis, date of diagnosis, age at diagnosis, and sex from the Swedish quality register SWIBREG and electronic patient records. Population data were collected from Statistics Sweden. The incidences for 2006-2010 (pre-outbreak) and 2011-2019 (post-outbreak) were evaluated by negative binomial regression analysis and presented as incidence rate ratios (IRRs). Data were analyzed for IBD, for UC and CD separately, and MC. RESULTS: During the study period, we identified 410 patients with new onset IBD and 155 new cases of MC. Overall, we found a trend toward an increased incidence of IBD post-outbreak (IRR 1.39, confidence interval (CI) 0.99-1.94). In individuals ≥40 years old, the post-outbreak incidence significantly increased for IBD (IRR 1.69, CI 1.13-2.51) and CD (IRR 2.23, CI 1.08-4.62). Post-outbreak incidence of MC increased 6-fold in all age groups (IRR 6.43, CI 2.78-14.87). CONCLUSIONS: The incidence of late-onset IBD and MC increased after the Cryptosporidium outbreak. Cryptosporidiosis may be an environmental risk factor for IBD and MC.

App-based self-management of urgency and mixed urinary incontinence in women: One-year follow-up.

AIMS: To evaluate the long-term effect of the Tät®II app for treatment of urgency (UUI) and mixed urinary incontinence (MUI). METHODS: Long-term follow-up of a randomized controlled trial, including 123 women ≥18 years old with UUI or MUI, without red-flag symptoms, and ≥2 leakages per week. All participants, regardless of group, had received the intervention, a treatment app, at the long-term follow-up. Long-term data were collected through web-based questionnaires 15 months after participants received the intervention. The app included pelvic floor muscle training, bladder training, psychoeducation, lifestyle advice, an exercise log, reminders, reinforcement messages, and tailored advice. The primary outcome was a change in incontinence symptoms (International Consultation on Incontinence Questionnaire [ICIQ]-Urinary Incontinence Short Form [ICIQ-UI SF]), from baseline to follow-up. Other outcomes were urgency symptoms (ICIQ-Overactive Bladder Module (ICIQ-OAB)), quality of life (ICIQ-Lower Urinary Tract Symptoms Quality of Life Module [ICIQ-LUTSqol]), and improvement (Patient's Global Impression of Improvement [PGI-I]). RESULTS: Of the 123 women, 102 (83%) completed the long-term follow-up. The ICIQ-UI SF mean score improved from 11.5 to 7.6 (mean difference 4.0, 95% CI 3.2-4.7). The ICIQ-OAB improved from 6.7 to 5.5 (mean difference 1.3, 95% CI 0.9-1.6) and the ICIQ-LUTSqol improved from 38.0 to 30.9 (mean difference 7.1, 95% CI 5.7-8.5). Of the 102 women, 74 (73%) reported improvement. CONCLUSIONS: Self-management with the Tät®II app for UUI and MUI had a significant effect across all outcome measures also long-term and might serve as an alternative first-line treatment for these conditions.

Cytomegalovirus seropositivity is associated with reduced risk of multiple sclerosis-a presymptomatic case-control study.

BACKGROUND AND PURPOSE: Epstein-Barr virus (EBV) and human herpesvirus 6A (HHV-6A) are associated with increased risk of multiple sclerosis (MS). Conversely, infection with cytomegalovirus (CMV) has been suggested to reduce the risk of MS but supporting data from presymptomatic studies are lacking. Here, it was sought to increase the understanding of CMV in MS aetiology. METHODS: A nested case-control study was performed with presymptomatically collected blood samples identified through crosslinkage of MS registries and Swedish biobanks. Serological antibody response against CMV, EBV and HHV-6A was determined using a bead-based multiplex assay. Odds ratio (OR) with 95% confidence interval (CI) for CMV seropositivity as a risk factor for MS was calculated by conditional logistic regression and adjusted for EBV and HHV-6A seropositivity. Potential interactions on the additive scale were analysed by calculating the attributable proportion due to interaction (AP). RESULTS: Serum samples from 670 pairs of matched cases and controls were included. CMV seropositivity was associated with a reduced risk for MS (OR = 0.70, 95% CI 0.56-0.88, p = 0.003). Statistical interactions on the additive scale were observed between seronegativity for CMV and seropositivity against HHV-6A (AP 0.34, 95% CI 0.06-0.61) and EBV antigen EBNA-1 (amino acid 385-420) at age 20-39 years (AP 0.37, 95% CI 0.09-0.65). CONCLUSIONS: Cytomegalovirus seropositivity is associated with a decreased risk for MS. The protective role for CMV infection in MS aetiology is further supported by the interactions between CMV seronegativity and EBV and HHV-6A seropositivity.

Anxiety and depression in women with urinary incontinence using E-health.

INTRODUCTION AND HYPOTHESIS: Previous studies have found high prevalence rates of anxiety and depression in women with urinary incontinence (UI). This study investigates the prevalence in women who had turned to eHealth for treatment of UI and identifies possible factors associated with depression. METHODS: We analyzed data from two randomized controlled trials evaluating eHealth treatment for UI, including 373 women with stress UI (SUI), urgency UI (UUI), or mixed UI (MUI). We used the Hospital Anxiety and Depression Scale (HADS) and defined a score of ≥8 as depression or anxiety. The ICIQ-UI-SF questionnaire was used to score incontinence severity. Logistic regression was used to determine factors associated with depression and anxiety. RESULTS: Women with UUI or MUI were older than women with SUI, mean age 58.3 vs 48.6 years (p = <0.001). Four out of five participating women had a university education. The prevalence of anxiety and depression in women with SUI was 12.4% and 3.2% respectively. In women with MUI/UUI, 13.8% had anxiety and 10.6% had depression. In multivariate analyses, the odds ratio of having depression was 4.2 (95% CI = 1.4-12.3) for women with MUI/UUI compared with SUI when controlling for other risk factors. CONCLUSION: The odds of depression in women with MUI/UUI were increased compared with SUI. The prevalence of anxiety and depression was considerably lower than reported in large cross-sectional surveys. Socioeconomic differences may partly explain this finding, as the use of eHealth still is more common among highly educated women.

Quality of life in women with urinary incontinence seeking care using e-health.

BACKGROUND: Quality of life (QoL) in women with urinary incontinence (UI) is mainly affected by UI severity, but it is also affected by the UI subtype, comorbidities, age, and socioeconomic status. e-Health is a new method for providing UI treatment. This study aimed to identify factors with the highest impact on QoL in women that turned to e-health for UI self-management. METHODS: We analysed data from three randomized controlled trials (RCTs) that evaluated e-health treatments for UI. We included baseline data for 373 women with stress urinary incontinence (SUI) and 123 women with urgency/mixed UI (UUI/MUI). All participants were recruited online, with no face-to-face contact. Participants completed two questionnaires: the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF, range: 0-21 points), for assessing UI severity, and the ICIQ Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol, range: 19-76 points), for assessing condition-specific quality of life (QoL). To identify factors that impacted QoL, we constructed a linear regression model. RESULTS: The mean ICIQ-LUTSqol score was 34.9 (SD 7.6). UI severity significantly affected QoL; the adjusted mean ICIQ-LUTSqol score increased by 1.5 points for each 1.0-point increase in the overall ICIQ-UI SF score (p < 0.001). The UI type also significantly affected QoL; the adjusted mean ICIQ-LUTSqol score was 2.5 points higher in women with UUI/MUI compared to those with SUI (p < 0.001). CONCLUSIONS: We found that women that turned to e-health for UI self-management advice had a reduced QoL, as shown previously among women seeking UI care through conventional avenues, and that the severity of leakage had a greater impact on QoL than the type of UI. Condition-specific factors impacted the QoL slightly less among women that turned to e-health, compared to women that sought help in ordinary care. Thus, e-health might have reached a new group of women in need of UI treatment.

A Mobile App for Self-management of Urgency and Mixed Urinary Incontinence in Women: Randomized Controlled Trial.

BACKGROUND: Many women experience urgency (UUI) and mixed (MUI) urinary incontinence but commonly hesitate to seek care. Treatment access and self-management for these conditions can be supported through eHealth approaches. OBJECTIVE: This study aimed to investigate the efficacy of the mobile app Tät II for self-management of UUI and MUI in women. METHODS: This randomized controlled trial included women ≥18 years old with UUI or MUI and ≥2 leakages per week. Those with red-flag symptoms were excluded. Participants were recruited via analog and digital advertisements and screened for initial selection through a web-based questionnaire. Data were collected using another questionnaire and a 2-day bladder diary. A telephone interview confirmed the symptom diagnosis. Participants were randomized (1:1) to receive access to a treatment app (including pelvic floor muscle training, bladder training, psychoeducation, lifestyle advice, tailored advice, exercise log, reinforcement messages, and reminders) or an information app (control group), with no external treatment guidance provided. The primary outcome was incontinence symptoms at the 15-week follow-up, measured using the International Consultation on Incontinence Questionnaire (ICIQ)-Urinary Incontinence Short Form (ICIQ-UI SF). Urgency symptoms were assessed using the ICIQ-Overactive Bladder Module (ICIQ-OAB) and quality of life using the ICIQ-Lower Urinary Tract Symptoms Quality of Life Module (ICIQ-LUTSqol). Incontinence episode frequency (IEF) was calculated per bladder diary entries. Improvement was measured using the Patient's Global Impression of Improvement. All outcomes were self-reported. Cure was defined as no leakages per the bladder diary. Intention-to-treat analysis was performed. RESULTS: Between April 2017 and March 2018, 123 women (mean age 58.3, SD 9.6 years) were randomized to the treatment (n=60, 2 lost to follow-up) or information (n=63) group. Of these, 35 (28%) women had UUI, and 88 (72%) had MUI. Mean ICIQ-UI SF score at follow-up was lower in the treatment group than in the information group (estimated difference -3.1, 95% CI -4.8 to -1.3). The estimated between-group difference was -1.8 (95% CI -2.8 to -0.99) for mean ICIQ-OAB score and -6.3 (95% CI -10.5 to -2.1) for the mean ICIQ-LUTSqol score at follow-up. IEF reduction from baseline to follow-up was greater in the treatment group (-10.5, IQR -17.5 to -3.5) than in the information group (P<.001). Improvement was reported by 87% (52/60) of treatment group participants and by 30% (19/63) of information group participants. The cure rate was 32% in the treatment group, and 6% in the information group (odds ratio 5.4, 95% CI 1.9-15.6; P=.002). About 67% (40/60) of the treatment group participants used the app more than thrice a week. CONCLUSIONS: The treatment app was effective for improving urgency and mixed incontinence in women. When self-management is appropriate, this app may be a good alternative to pharmacological treatment or other conservative management, thus increasing access to care.

Risks of asphyxia-related neonatal complications in offspring of mothers with type 1 or type 2 diabetes: the impact of maternal overweight and obesity.

AIMS/HYPOTHESIS: We aimed to compare the risks of severe asphyxia-related neonatal complications in the offspring of mothers with type 1 or type 2 diabetes, and to assess the impact of maternal overweight/obesity on these risks. METHODS: This was a population-based study of 1,343,751 live-born singleton infants in Sweden between 1997 and 2011, including 5941 and 711 infants of mothers with type 1 and type 2 diabetes, respectively. ORs with 95% CIs were calculated for low Apgar score (0-6) at 5 min after birth, hypoxic ischaemic encephalopathy and neonatal seizures. RESULTS: The rates of a low Apgar score were 0.9%, 2.6% and 2.1% in the offspring of mothers without diabetes or with type 1 or type 2 diabetes, respectively. After controlling for maternal confounders (including BMI), the risk of a low Apgar score increased in the offspring of mothers with type 1 diabetes (OR 2.67, 95% CI 2.23, 3.20) but not in the offspring of mothers with type 2 diabetes (OR 1.25, 95% CI 0.66, 2.35). The ORs of hypoxic ischaemic encephalopathy or neonatal seizures were increased in the offspring of mothers with type 1 diabetes (OR 3.41, 95% CI 2.58, 4.49) and type 2 diabetes (OR 2.54, 95% CI 1.13, 5.69). Maternal overweight/obesity was a risk factor for asphyxia-related neonatal complications and low Apgar scores in the offspring of mothers with type 1 diabetes and mothers without diabetes. CONCLUSIONS/INTERPRETATION: The risks of a low Apgar score and severe asphyxia-related neonatal complications are increased in the offspring of mothers with type 1 or type 2 diabetes. Maternal overweight/obesity is an important contributing factor.

High Maternal Body Mass Index in Early Pregnancy and Risks of Stillbirth and Infant Mortality-A Population-Based Sibling Study in Sweden.

In a population-based case-control study, we investigated whether familial confounding influenced the associations between maternal overweight/obesity and risks of stillbirth and infant mortality by including both population and sister controls. Using nationwide data from the Swedish Medical Birth Register (1992-2011), we included all primiparous women with singleton births who also had a sister with a first birth during that time period. We used logistic regression analyses to calculate odds ratios (and 95% confidence intervals) adjusted for maternal age, height, smoking habits, education, and time period (5-year groups) of child's birth. Body mass index (BMI) was calculated as weight (kg)/height (m)(2) Compared with population controls with a normal BMI (18.5-24.9), stillbirth risk increased with increasing BMI (BMI 25-29.9: odds ratio (OR) = 1.51 (95% confidence interval (CI): 1.21, 1.89); BMI 30-34.9: OR = 1.77 (95% CI: 1.24, 2.50); BMI ≥35: OR = 3.16 (95% CI: 2.10, 4.76)). The sister case-control analyses revealed similar results. Offspring of obese women (BMI ≥30) had an increased risk of infant mortality when population controls were used (OR = 2.41, 95% CI: 1.83, 3.16), and an even higher risk was obtained when sister controls were used (OR = 4.04, 95% CI: 2.25, 7.25). We conclude that obesity in early pregnancy is associated with increased risks of stillbirth and infant mortality independently of genetic and early environmental risk factors shared within families.

Tobacco smoking cessation and improved gastroesophageal reflux: a prospective population-based cohort study: the HUNT study.

OBJECTIVES: Tobacco smoking increases the risk of gastroesophageal reflux symptoms (GERS), but whether tobacco smoking cessation improves GERS is unclear. The aim of this study was to clarify if tobacco smoking cessation improves GERS. METHODS: The study was based on the Nord-Trøndelag health study (the HUNT study), a prospective population-based cohort study conducted from 1995-1997 to 2006-2009 in Nord-Trøndelag County, Norway. All residents of the county from 20 years of age were invited. The study included 29,610 individuals (61% response rate) who reported whether they had heartburn or acid regurgitation. The association between tobacco smoking cessation and improvement in GERS was assessed by logistic regression, providing odds ratios (ORs) with 95% confidence intervals (CIs). The analyses were stratified by antireflux medication, and the results were adjusted for sex, age, body mass index (BMI), alcohol consumption, education, and physical exercise. Subgroup analyses were also stratified by BMI. RESULTS: Among individuals using antireflux medication at least weekly, cessation of daily tobacco smoking was associated with improvement in GERS from severe to no or minor complaints (adjusted OR 1.78; 95% CI: 1.07-2.97), compared with persistent daily smoking. This association was present among individuals within the normal range of BMI (OR 5.67; 95% CI: 1.36-23.64), but not among overweight individuals. There was no association between tobacco smoking cessation and GERS status among individuals with minor GERS or individuals using antireflux medication less than weekly. CONCLUSIONS: Tobacco smoking cessation was associated with improvement in severe GERS only in individuals of normal BMI using antireflux medication at least weekly, but not in other individual with GERS.
